PATENT JOHN H. WVAGNER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE SMITH CONSOLIDATION COMPANY, OF SAME PLACE.

MACHINE FOR CONSOLIDATING LOOSE MATERIALS INTO SOLID BLOCKS.

SPECIFICATION forming part of Letters Patent No. 290,293, dated December 18, 1883.

Application filed September 11, 1852. (No model.)

To all whom, it may concern:

Be it known that I, JOHN H. WAGNER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Consolidating Loose Materials into Solid Blocks, of which the following is a specification.

My invention relates to certain improve ments on the machine invented by William Harrold Smith for consolidating various loose materials into solid self-coherent blocks; and it relates, more particularly, to the form of the molds and the mechanism employed for raising and revolving the same.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure 1 is an elevation, partly in section, of a device embodying my invention. Fig. 2 is a side view, and Fig. 3 is a detail view of the connecting-arm.

In the drawings, A represents the main frame of the machine, upon which the'molds B are supported. The molds are secured to the central block or casting, C, which is provided with a central shaft, C, around which the molds rotate. The central block, C, is

provided at its base with a circular bevel face or track, 0, which rests or travels upon the bevel-frictions D. y

In Fig. 1 the molds are represented as resting upon the anvil E. The shafts D, to which the bevel frictions are secured, are mounted in eccentric sleeves F, which are provided with crank-arms F, connected with crank-arms G on the rock-shaft H by the adjustable connecting-bar K. By rocking the shaft H, the eccentric sleeves F are turned so as to bear the bevel-frictions against the block C and raise the molds so they will clear the anvil, and as one of the bevel-frictions receives a rotary motion from the driving-pulley I the molds will of course at the same instant begin to revolve. By turning the rockshaft in the opposite direction, the molds may be again lowered upon theanvil. The rockshaft is provided with a crank-arm, J, which is operated by and connected to the piston L of the steam-cylinder M by means of the slotted slide m, which slides up and down. on the guide-bar m.

m" is the slot in said slide, in which fits the wrist-pin m on the end of the crank-arm.

N is the steam-chest, which is provided with a valve through which steam is admitted to the cylinder, and n isthe lever for operating the valve.

The length of the connecting-bars K may be varied by turning the turnbuckle It so as to accurately adjust the throw of the eccentric sleeves F. on opposite sides of the sleeves F, so that the forward or horizontal motion of the bevelfrictions, as they are raised against the baseblock of the molds, will both correspondwith the direction the molds are to revolve. The molds B, which are made entirely of cast metal, are provided with circular projections or corrugations b on their surface, which gradually increase in thickness from top to base of the mold, so as to afford the greatest strength at the base, and with the least amount of weight of metal, the circular cor= rugations serving to strengthen the mold much the same as wrought-iron bands shrunk upon the molds, but at very much less cost or expense than by use of wrought-iron bands.

In the drawings I have shown two bevelfrictions, but one or both or a greater numbe! may be used, if desired; and I have shown only one of the bevel-frictions provided with a driving-pulley, but a drivingpulley may be employed for each, if desired.

The corrugations on the surface of the mold also very" much facilitate the perforation of the molds for the purpose of giving vent for the escape of air from the material being consolidated.

I claim- 1 1. The combination of the molds provided with a circular bevel-track, c, on their baseblock, with a revolving bevel-friction mounted in an eccentric sleeve, and mechanism for turning said sleeve, whereby the molds are at once raised and revolved, substantially as specified.

2. The combination of the revolving bevelfriction, an eccentric sleeve in which the same The crank-arms F are placed is mounted, provided with an arm and mechanism for connecting the same with the piston of a steam-cylinder, whereby the same is 0pcrated, substantially as specified.

3. The combination of the molds 13, central block 0, provided with circular beveltrack a, revolving bevel-frictions D, mounted in eccentric sleeves F, sleeve-arms F, eon-
